Contributions to the glibc project require copyright assignment to the FSF. Please see our contribution checklist: https://sourceware.org/glibc/wiki/Contribution%20checklist#FSF_copyright_Assignment You will need a corporate assignment, your employer will have to sign the assignment paperwork. I suggest you start by following this process: http://git.savannah.gnu.org/cgit/gnulib.git/plain/doc/Copyright/request-assign.future And answering the question "Do you have an employer who might have a basis to claim to own your changes?" is the most important question, since it starts the process of corporate copyright assignment.

I look forward to reviewing your patches! :-)
This patch series fix Shanghai Zhaoxin processor CPU Vendor ID detection problem in glibc sysdep module. Current glibc doesn't recognize Zhaoxin CPU Vendor ID("CentaurHauls" and "Shanghai") and set kind to arch_kind_other. These lead to incorrect result of __cache_sysconf(), incorrect value for variables like __x86_shared_cache_size, and fail of test case tst-get-cpu-features. Background: Shanghai Zhaoxin Semiconductor Co., Ltd("Zhaoxin"), established in 2013, headquartered in Zhangjiang, Shanghai, China. Zhaoxin aims at providing general-purpose x86 processors.
